Indian Muntjac Deer Skin Fibroblast Cells

A fibroblast cell line established from a skin biopsy of an adult male, the Indian Muntjac deer epidermis line is commonly used in laboratories around the world, especially for chromosome studies. Members of the family Cervidae, Muntjacs are barking deer that emit their characteristic sound when they feel threatened or alarmed.

The normal (non-transformed) Indian Muntjac cell line is susceptible to the herpes simplex virus, vaccinia virus, and vesicular stomatitis virus (Indiana strain), but is resistant to poliovirus 1. Recent tests have demonstrated that the cells produce both detectable bovine viral diarrhea virus (BVDV) antigens and infectious BVDV virions. Muntjac cells are negative for reverse transcriptase, indicating the lack of integral retrovirus genomes.

Cell lines derived from the Indian Muntjac have been of significant scientific interest primarily because the animal possesses the fewest number of diploid chromosomes of all mammals, with only six chromosomes in the female and seven in the male. Such a small number of chromosomes makes Indian Muntjac cells an ideal candidate for mitosis research. Moreover, in recent years, Indian Muntjac cells have gained a reputation for their usefulness as a model to study telomere biology. Telomeres, the regions of DNA that occur at the end of chromosomes, are at the center of many modern studies involving the aging of organisms and cell senescence. It is generally believed that the shortening of telomeres, which occurs during the division of most cells, is responsible for age-related cellular malfunction and death. Thus, telomeres are also of interest in regard to cancer, since tumor cells are often able to proliferate unhindered by the passage of time due to various mechanisms that avoid the shortening of chromosomal telomeres.
